How many Intel based machines have ECC cache? My guess is not many.

Wrong guess. I believe they all do.

As far as I know, Sun has not fingered the supplier of the affected cache, merely saying they are no longer a supplier. Does anybody know their identity?

Charles, doesn't matter, Sun "should have used protection."

The type of errors that occur 99.999% (most) of the time from alpha particles, gamma rays or the like are soft, singe bit, and are correctable with the right kind of ECC. Cache ECC was used in mainframe machines as early as the 80s. Main memory ECC was used in mainframes in the 70s. As was pointed out, Intel based started with the Pentium II Xeon.

Doesn't matter though, Sun has the mystique right now.

Charles - CPQ ProLiant servers have had ECC cache since 1996. I did not realize that the high end UE machines did NOT have ECC cache - this has been pretty much standard practice for 5 years. CPQ machines also have error correction on the I/O bus.
